Where to purchase just a few gears?
where I used to work, they had a big catalog from Boston Gear. must have
been two inches thick. Not sure if they are still around but worth a try. -- don paolino "Norm Dresner" wrote in message ... I'm an Electrical Engineer who's creating a one-off piece of instrumentation that needs to include two adjustment potentiometers that are controlled by a single shaft. These are multi-turn pots and they need to be "perfectly" synchronized throughout their 10-20 turn range over a long period of time and many adjustments. To avoid the complications of backlash, I think I need just three gears (rather than belts or chains), one on a master shaft and two slaves -- although I could probably also do it with just two gears, the mechanical construction is a bit simpler if I have identical mounting for the two pots. This isn't a production item, it's one-off. The pots are just under 1" in diameter and the shafts are round and 1/4" diameter. I'd appreciate a URL or three for some place(s) to purchase these gears and similar things like this which come up from time to time. TIA Norm |

Small Parts, Inc., has it too -- significantly smaller selection of gears but a no-hassle retail ordering policy. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com |
